If im understanding it correctly (and its a good chance im not) the universe is divided into 3 torus shaped kinda like a donut. Whats this about travaling in a straight line and comeing back to where you started well kinda were you started, but if you can then light also must do the same thing. Im wondering if the numbers roughly a hundred billion galaxies with a hundred billion stars is grossly over estimated, could we just be seeing the light of our own galaxy doing countless loops around the universe and we are seeing it over and over from diffrent angles giving the illusion of countless galaxies, its just like reflections in a room full of mirrors. I like the idea of a vast universe growing by leeps and bounds but now i hear crazy stuff like this and now my head hurts. Someone plz make the universe make sense again i wanna live in an ever expanding unvierse not some chezzy arcade game where i can jump out the right side of the screen just to come back on the left.

Torus is simply another word for a donut shaped surface. There are many theories of the shape and size of the universe, and the one you refer to is just another for advanced mathematicians and physicists to play with. Likely, it is also an attempt to describe one of the mathematical constructs that actually cannot be visualized with our three dimensional perspective.

Experiments with astronomical distances show that space is curved, but considering that the universe is about 10 billion light years in size, you wouldn't have to be concerned about some unimaginable house of mirrors affect. Curved space is simply the nature of a cosmos made of bodies held together by gravity. From what we can see with telescopic arrays and can test with spectroscopy and the doppler affect, we know we are not seeing the same bodies over and over from different perspectives. There are many other experiments including radiation measures and measures of the amount of matter the universe should contain which confirm the vastness of galactic numbers.

If you assume that we are in an expanding universe that contains roughly 100 billion galaxies with trillions to septillions of individual stars of many types, then that is a fair enough way to think of the unimaginable scope and diversity of universe.

Its the same thing as Mercury Sable. And yes you can move from one to another at a car dealership.
